I purchased BP in 2006 and it has always been a joy to see it in bloom. In the 10 years I have had it, it had never been moved until this year when I finally divided it to sell at our club sale in June. It was about 20 fans when I separated it. I believe it would have been more had I divided it after five years. It was a very tight clump to divide.
It usually has 2-3 way branching close to the top and anywhere between 10-18 buds, which you might be able to see in the picture below.
Although it is registered as ML bloomer, in my zone 6b garden in 2015, it bloomed from June 13th thru July 4th, so a good three weeks of bloom. And it definitely has a nice, sturdy 32" scape to hold up the blooms. I've never noticed rust on it.
The database shows it as an EMO (early morning opener), but I really couldn't say whether I've ever noticed this trait or not.
